Concern level

Moderate concern

Anethole is a naturally occurring aromatic ether used primarily as a fragrance/flavor ingredient, especially in anise-, fennel-, and licorice-like scent profiles. In cosmetics it functions mainly as a scent component rather than a skin-benefit active. It is a volatile, lipophilic molecule with low water solubility and a characteristic sweet, spicy odor.

Interactions

Risks & Warnings

Can cause skin sensitization or irritation, particularly in leave-on products or for fragrance-sensitive users. As a fragrance allergen, it may trigger redness, itching, or dermatitis in susceptible individuals. Animal/toxicology references note systemic activity at high doses, so topical cosmetic use should remain low and fragrance-limited. Avoid use on already irritated or compromised skin when possible.
